Prof. Holzinger is right. The former Secretary of the Sullivant Moss' 

 Chapter felt her work to be largely of an educational nature, and for fear of 

 nipping a bud prematurely, took extra pains with "scraps" and often con- 

 sumed hours of time in their determination only to find the collector had no 

 more material, so all that labor was wasted. Why? Because, if that little 

 scrap contained a peculiar form — albeit [of a well known species, it has only 

 too frequently happened that a new variety or species even has been de- 

 scribed, only later to have it find its true place as one in a long link of inter- 

 mediate forms in a well known series. 



The moral is: send good sized specimens for determination with proper 

 data. A. M. S. 



REPORT OF THE LICHEN DEPARTflENT, 



A year ago the Lichen Herbarium belonging to the Moss Chapter was - 

 placed in my hands. At that time it contained fifty specimens, representing 

 eighteen genera and forty-four species. At the present time there are one 

 hundred and seventy specimens, representing twenty-seven genera and 

 ninety-five species and varieties. Many of the specimens have been contrib- 

 uted by the members of the Moss Chapter, and I hope during the com'ing 3'ear 

 there will be many more contributions to the Chapter Herbarium. 



I would urge all who are interested in the Lichens to make local collec- 

 tions, taking pains to collect good [sized specimens and in fruit where it is 

 possible. The Lichens should be pressed lightly while damp, if allowed to 

 dry without pressing they are much more brittle. It would be well if more of 

 the members would offer specimens for distribution, in this way they will gain 

 experience and secure specimens from other localities which will be useful 

 for comparison. 



A number of specimens from California, Montana, Oregon and Lower 

 California have been added during the past year. 



The many letters asking for help in determining lichens and the requests 

 for the offerings prove that the interest is growing in the study of these 

 plants. Respectfully submitted, Carolyn W. Harris.
